Background: Symptomatic disseminated myxopapillary ependymoma (MPE) in a young person presents a daunting challenge because the risks of prolonged prone positioning and spinal cord injury may outweigh the likelihood of attaining the benefit of gross total resection.

Observations: The authors reported the case of a 15-year-old girl with five discrete recurrent spinal cord ependymomas. The patient received a 25-hour surgical procedure for gross total resection of the tumors and fusion over an approximately 33-hour period.

Article Synopsis
  • The study compared the clinical use and costs of autologous bone flap (ABF) and synthetic flap (SF) cranioplasties, finding that while the total number of procedures decreased, the use of SF increased significantly.
  • The median hospital charge for SF cranioplasty was $31,200 higher than for ABF, and about 20% of patients were readmitted for infection-related surgery.
  • Female patients and those treated with SF had a higher likelihood of readmission for reoperation, but overall, patients were less likely to be readmitted for infection in more recent years.

Article Synopsis
  • - The study aimed to analyze how the COVID-19 pandemic affected hospital visits and treatment processes for traumatic brain injuries (TBIs), intending to guide future health policies.
  • - Data from the Michigan Trauma Quality Improvement Program showed an initial 18% drop in TBI cases during the first part of the COVID-19 period, followed by a 16% increase towards the end, with overall rates similar to pre-pandemic levels.
  • - Findings indicated that more TBI patients were arriving at the hospital later, and there was an increase in pressure ulcers during the pandemic, but no significant differences in severity or crucial outcomes like mortality or ICU stays between the two periods.

Article Synopsis
  • The study investigates the readmission rates for patients with malignant brain tumors undergoing two different procedures: Laser Interstitial Thermal Therapy (LITT) and Stereotactic Needle Biopsy (SNB).
  • The results show similar hospital stay lengths and discharge rates for both procedures, with no significant differences in readmission rates within 30 or 90 days.
  • The findings suggest that LITT is as safe as SNB regarding the risk of readmission, supporting its use in treating malignant brain cancers.

Background/objective: The COVID-19 pandemic has had a profound impact on the global delivery of health care. Recent data suggest a possible impact of the pandemic on patterns of neurotrauma. The aim was to assess the impact of the pandemic on the incidence of neurotrauma, with a focus on cranial gunshot wounds (cGSWs) at a large Midwestern level 1 trauma center.

Purpose: Understanding factors that influence technology diffusion is central to clinical translation of novel therapies. We characterized the pattern of adoption for laser interstitial thermal therapy (LITT), also known as stereotactic laser ablation (SLA), in neuro-oncology using the National Inpatient Sample (NIS) database.

Methods: We identified patients age ≥ 18 in the NIS (2012-2018) with a diagnosis of primary or metastatic brain tumor that underwent LITT or craniotomy.

Coupled with the rise of data science and machine learning, the increasing availability of digitized health and wellness data has provided an exciting opportunity for complex analyses of problems throughout the healthcare domain. Whereas many early works focused on a particular aspect of patient care, often drawing on data from a specific clinical or administrative source, it has become clear such a single-source approach is insufficient to capture the complexity of the human condition. Instead, adequately modeling health and wellness problems requires the ability to draw upon data spanning multiple facets of an individual's biology, their care, and the social aspects of their life.

Nonstandard insurers suffer from a peculiar variant of fraud wherein an overwhelming majority of claims have the semblance of fraud. We show that state-of-the-art fraud detection performs poorly when deployed at underwriting. Our proposed framework "FraudBuster" represents a new paradigm in predicting segments of fraud at underwriting in an interpretable and regulation compliant manner.

Medication non-adherence is a pressing concern among seniors, leading to a lower quality of life and higher healthcare costs. While mobile applications provide a viable medium for medication management, their utility can be limited without tackling the specific needs of seniors and facilitating the active involvement of care providers. To address these limitations, we are developing a tablet-based application designed specifically for seniors to track their medications and a web portal for their care providers to track medication adherence.
